5.9 TACACS+ Commands
TACACS+ provides access control for networked devices via one or more centralized
servers. Similar to RADIUS, this protocol simplifies authentication by making use of a
single database that can be shared by many clients on a large network. TACACS+ is
based on the TACACS protocol (described in RFC1492) but additionally provides for
separate authentication, authorization, and accounting services. The original protocol
was UDP based with messages passed in clear text over the network; TACACS+ uses
TCP to ensure reliable delivery and a shared key configured on the client and daemon
server to encrypt all messages.
5.9.1 tacacs-server host
Use the tacacs-server host command in Global Configuration mode to configure a
TACACS+ server. This command enters into the TACACS+ configuration mode. The
<ip-address> parameter is the IP address of the TACACS+ server. To specify multiple
hosts, multiple
tacacs-server host commands can be used.
